I have 4 of this tool. They are among the most robust and durable tools made. They will last for years with reasonable care. The power, design, and hinge are amazing. I know stanley/black and Decker love to change battery platforms instead of updating the tools, which leaves some of us behind for no reason. For that reason, I'm not going to wish for lithium. Instead of updating the batteries, they would do a bonehead and make my tools obsolete. Enjoy this tool for what it is, a SUPERIOR screwdriver.
